Vancouver, British Columbia--(Newsfile Corp. - April 29, 2025) - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce further results of chemical assay (U3O8) grades from 8 boreholes drilled in late 2024 at the Copper Mountain Uranium Project in Wyoming, USA (Figure 1).
Chemical assays (U3O8) have been compared against the previously reportedequivalent spectral gamma probe uranium results (eU3O8) and confirm extensive high-grade uranium mineralisation at the Canning Deposit. Furthermore, certain U3O8intervals are higher, and lower, than their previously reportede U3O8grades, indicating secular disequilibrium is present in the system. Using a 1,000 ppm cut-off, the U3O8grades (from chemical assay) reported here are on average 50% higher than previously-reported eU3O8grades (equivalent gamma probe grades) over the same intervals. Using a 200 ppm cut-off, they are on average 24% higher. These increases relative to probe grades are consistent with assays of the first 20 boreholes the Company reported on March 17, 2025. Results from the remaining 6 boreholes are pending and will be reported in due course.
Highlights
-
Using a 200 ppm U3O8cut-off, chemical grades are on average 24% higher than previously-reportedequivalent (spectral gamma probe) uranium grades. Using a 500 ppm cut-off, the average grades are 43% higher, and using a 1,000 ppm cut-off, average grades are 50% higher. There is both positive and negative variance (disequilibrium).

Thomas Lamb, Myriad's CEO, commented: _"These are excellent results which level up the Copper Mountain project. Confirmed grades average significantly higher than the equivalent gamma probe uranium grades and suggest Union Pacific may have taken a conservative approach to accounting for disequilibrium at Copper Mountain. This may have positive implications for historic resource estimates and grades. I mentioned in our previous release relating to assays that it is possible a significant volume of uranium mineralisation was not detected at Copper Mountain by the 1970-era gamma probes, which would be very exciting for the project. But also potentially very significant is what has been emphasised by this group of assays, which is that higher-grade zones are on average 50% more uraniferous than previously thought. This could have supportive implications for future resource estimation and mine planning, for example. However this must be treated as speculation._"

George van der Walt, Myriad's consulting geologist and technical advisor, commented: "I am pleased that assay grades continue to hold up against the previously reported equivalent gamma grades."

Highlights of significant intervals have been selected to represent a grade-thickness product (GT) of greater than 0.3 ft%, which is equivalent to 1,000 ppm U3O8over 3 feet.
Updated significant chemical assay intervals with a GT >0.15 ft% (equivalent to 500 ppm over 3 feet), and their equivalent spectral gamma probe intervals are included in Table 1 below. Note that Appendix 1 provides all grade intervals at (a) 1,000 ppm (0.10%) U3O8cut-off, 500 ppm (0.05%) U3O8cut-off and (b) 200 ppm (0.02%) U3O8cut-off.

Notes: 1) The interval lengths are "down the hole" and may not represent true width intervals as the exact nature of the mineralization distribution has not been determined yet. However, most of the holes were drilled at an inclination of 50 degrees to test a model that indicates steeply dipping mineralisation. 2) eU3O8is the radiometric equivalent U3O8derived from a calibrated total gamma downhole probe. 3) U3O8is the chemical assay of mineralized split core samples or RC cuttings. 4) Core sampling was conducted at 3 feet intervals, adjusted to minimum of 1 foot, where appropriate. 5) Reverse Circulation sampling was conducted at 5 feet intervals, according to the drilling procedure. 6) Assay interval depths have been adjusted to spectral gamma probe depths, where appropriate. 7) Intervals were composited above a cut-off grade of 500 ppm U3O8, with grade below cut-off less than 1 foot being included in the total interval. 8) Abbreviations: DD = Diamond Drill, RC = Reverse Circulation. 9) "High-grade uranium" is defined by the Company as composite results with >1000 ppm U3O8and no greater than 1-foot continuous internal dilution.
The boreholes represent a combination of diamond core and reverse circulation drilling that was planned to verify mineralization identified in drilling by Union Pacific in the late 1970s and test a grade shell model (above 0.05% eU3O8) created from cross-sections, as reported hereand here. All reported assay results are represented by the borehole locations indicated on Figure 1 and Table 2 below.

Drilling
Drilling was undertaken by Harris Exploration using two diamond core (DD) rigs producing HQ (63.5 mm / 2.5 in) core diameter and 96 mm (3.78 in) in hole diameter, and one reverse circulation (RC) rig using a 140 mm (5.5 in) hammer bit. Core samples were packed into core trays and transported to Riverton for further processing. RC hole runs were drilled at 5 ft intervals and split on site by a rig-mounted cyclone splitter to produce two representative samples that were then transported to Riverton for further processing.
Downhole Logging
Downhole logging was performed by DGI Geoscience (DGI) using a combination of Spectral Gamma Ray (SGR) probe for gamma data, and Optical Televiewer and/or Acoustic Televiewer for structural data. The probes are manufactured by Mount Sopris Instruments with details as follows:
QL40 SGR BGO (Sx): Measures the energy of gamma emissions from natural sources within formations crossed by a borehole. It counts the number of gamma emissions at each energy level aiding in lithological determination and correlation. The Probe use a Bismuth Germanium Oxide scintillation crystal. QL40 SGR 2G CeBr3 (Sx): Measures the energy of gamma emissions from natural sources within formations crossed by a borehole. It counts the number of gamma emissions at each energy level aiding in lithological determination and correlation. The probe uses a CeBr3 (Cerium Bromide) scintillation crystal. QL 40 ABI 2G (At, Gr): Captures high-resolution, oriented images of the borehole wall, allowing the orientation of acoustically visible features to be determined. This includes fractures, bedding/rock fabric, breakouts, bedding planes and other structural features. Contains a built in Natural Gamma sensor that measures the gamma emissions from natural sources in the formation. QL OBI 2G (Ot, Gr): Captures a high-resolution, oriented image of the borehole wall using a CMOS digital image sensor, allowing the orientation of features to be determined. This includes fractures, bedding/rock fabric, veins, lithological contacts, etc. Contains a built in Natural Gamma sensor that measures the gamma emissions from natural sources in the formation.
